Title: Production of lattice for plate of lead storage battery
Inventor: SEKIGUCHI HIDEO
IPC: H01M4/73
Filed: 1981-03-11
Abstract: PURPOSE:To improve the adhesion of an active substance and to reduce cyclic deterioration by a method wherein a state teeming with unevenness is given to the surface of a cast lattice made from alloy of Pb-Ca series so as to increases the surface area of the lattice. CONSTITUTION:It is known as a blast process to blow grains (hard enough to form unevenness on the surface of a lattice) against the surface of the lattice at high velocity, and there are sand and grid blast methods for providing the blast process. The unevenness is produced because part of the lattice is shaved off when the grains collide with the lattice. 1 indicates the period of the self-discharge maintained by a battery having a plate made with the blast process, while 2 shows the characteristics of the period of the self-discharge maintained by a battery having a plate prepared without the blast process. As illustrated by the graphic representation, the one having a plate prepared with the blast process shows less deterioration in its life.

Title: Center positioning method for reformed image of medical image diagnosis device
Inventor: TAKIGUCHI OSAMU
IPC: A61B6/03
Filed: 1990-02-16
Abstract: PURPOSE:To always obtain an image that is free from a center position error by setting the center position of a tomographic image with use of a fluoroscopic image having >=2 directions. CONSTITUTION:When a 2-dimensional tomographic image or a 3-dimensional image is reformed, the reformation center surface are designated onto plural fluoroscopic images obtained in two directions A and B orthogonal to each other. Then a center point O or a center line of a desired reformed image is decided based on the intersecting line set between those designated center point or center line. In other words, an intersecting center position between an A-direction image center line 14 set on an image center surface viewed from the direction of an arrow A and a B-direction image center line 15 set on an image center surface viewed from the direction of an arrow B is decided. Thus it is possible to follow a desired center position even in the measurement of a bent area especially in the continuous magnified measurement. Then an image free from an error of a center position is always obtained in a simple way.

Abstract: PURPOSE:To shorten the time for manufacturing, and to obtain a substrate of high reliability from the viewpoint of quality by mixing a metal catalytic nucleus, for electrolss plating process, with a translucent conductive film at the time of forming the translucent conductive film on a translucent insulating plate. CONSTITUTION:A metal catalytic nucleus 13 for electroless plating process, such as gold, silver, platinum or palladium, is at a certain ratio dispersed throughout and added to the composition formed out of metal oxide material such as indium oxide(In2 O3) or tin dioxide (SnO2), on a translucent insulating film 11 such as glass, so that a translucent conductive film 12 is formed by using a sputtering device. Namely, at the time of forming the translucent conductive film 12 on the translucent insulating plate 11, the metal catalytic nucleus 13 for electroless plating process is incorporated into the translucent conductive film 12. The metal catalytic nucleus 13 can thus be formed only in a pattern 15 of the the translucent conductive film 12. Since a metallic film will not be formed on the exposed surface of the outside of the translucent insulating plate 11, unlike the case with the conventional method, a substrate of high reliability in quality can be obtained, while the time for manufacturing can be shortened.

IPC: G01N15/02
Filed: 1986-02-20
Abstract: PURPOSE:To measure the concentration of particles in a gas flow accurately in a short time by picking up and processing the image of the particles optically. CONSTITUTION:When gas flowing in a duct 1 as shown by an arrow 2 is irradiated with slit light 11 with constant width from a laser light source 10, only smoke dust 3 in the space that the light 11 penetrates reflects the light 11. Then, the smoke dust 3 is photographed by a high-resolution camera 12 arranged almost at right angles to the light 11. The light source 10 moves in parallel to the photographic direction of the camera 12 as shown by an arrow 15, so the camera 12 take a photograph with the irradiated light 11 at a specific position of the arrow 15. Photographed pictures at respective irradiation positions are outputted to an arithmetic device 13 as an image signal. The device 13 performs image processing on the basis of the image signal to calculate the concentration of the smoke dust in the gas flow and the result is displayed on an image display device 14. Thus, the fluid is not sampled, so high measurement accuracy is maintained all the time and respective pieces of image information are processed in real time, so the measurement result is obtained in a short time.

Abstract: PURPOSE: To let the sensor respond only to the magnitude of signal magnetic fields and eliminate its output fluctuations owing to the rotation of a detecting element within the position signal magnetic fields by applying bias magnetic fields of respectively opposite directions to orthogonally disposed ferromagnetic material members.

On the other hand, the non-contrast-medium picture on the position A collected at the initial rotation is read out and sent to the element 44 and a picture obtained by mutually subtracting the preceding and current pictures is displayed on a picture monitoring device 45.  A cancel effect between the two pictures can be observed at a glance by observing the displayed picture, and if the two pictures are not completely canceled, a deviation is caused between the two pictures.

Abstract: PROBLEM TO BE SOLVED: To prevent the bottom surface of a cooking vessel or the like from being locally superheated by changing the forming part of a flame with the lapse of time by turning a flame port part even when a high load combustion burner is used. SOLUTION: This cooking stove has the flame port part 2 of a high load combustion burner 1 supported on a plane so as to be rotated and performs a combustion while the flame port part is rotated go that a flame forming part is varied with the lapse of time. While a single flame port part may be provided, a plurality of flame port parts may be provided and rotated concentrically. Therefore, (a) even when the high load combustion burner is used, a cooking vessel such as a pan is not locally superheated. (b) Thermal efficiency, which has been conventionally about 40% at its maximum. is raised up to approximately 60 to 70%. (c) Since the quantity of the heat loss of exhaust gas is decreased, the rise of an ambient temperature is suppressed and a work environment is more improved than a conventional one. (d).  Since the quantity of combustion air can be precisely set, NOx is relatively easily lowered.

Title: Dual wavelength anti-reflection film
Inventor: IRIE NORIYUKI
IPC: G02B1/115
Filed: 1994-03-04
Abstract: PURPOSE:To obtain a dual wavelength anti-reflection film low in film absorption, high in durability against laser and wide in anti-reflection zone by forming the anti-reflection film from an alternate layers of only an inorganic fluoride. CONSTITUTION:In the dual wavelength anti-reflection film having the minimum reflectance in the vicinity of the 1st wavelength of 248.4nm, and in the vicinity of the 2nd wavelength longer than the 1st wavelength, the anti-reflection film is constituted of multilayers consisting of high refractive index layers 3 and low refractive index layers 2 arranged respectively alternately. Inorganic fluoride is used for the high refractive index layer 3 and the low refractive index layer 2. For example, NdF3 or LaF2 is used as the material of the high refractive index layer 3 and MgF2 or AlF3 as the material of the low refractive index layer 2. Since the inorganic fluoride crystal has <=200nm transmission limiting wavelength, an absorption loss in the vicinity of the 1st wavelength of 248.4nm is extremely small. Then, the anti-reflection film having low absorption loss and high durability against laser is obtained by forming the anti-reflection film of the alternately arranged layers made of only inorganic fluoride.
